Peter Hawman is a Postdoctoral Research Associate at the Center for Geospatial Research, Geography of Department at the University of Georgia and with the Georgia Coastal Ecosystems Long Term Ecological Research (GCE-LTER) site on Sapelo Island, GA. He is also Co-I on a NASA Carbon Monitoring System project “A tide-robust high-resolution Blue Carbon product for fragmented coastal marshes”. His research is focused on tidal marsh carbon exchange and scaling ecosystem processes using remote sensing. Currently, he is working on projects developing scale-up methods and machine learning models to combine eddy covariance flux towers, lateral fluxes, and satellite datasets for long-term biophysical status assessments and carbon storage in coastal wetlands. Additionally, he is synthesizing coastal wetland flux tower sites across the US Atlantic coast and integrating remote sensing data with plant productivity and climate drivers to analyze spatio-temporal variability and tidal marsh resiliency. Outside of research, Peter enjoys birding, amateur astronomy, and gardening with his wife, Amy.
